Answer:
80 miles
Step-by-step explanation:
Speed = distance / time
Speed = 40/45
= 0.89miles/minute
If she continues at this speed, she will cover;
0.89 = distance/ 90
distance = 0.89*90
= 80 miles
Answer:
8/3 km
Step-by-step explanation:
we can represent the given information on a table:
Kilometers time (hours)
2/5 ⇔ 1 1/2
and since we want to know how many kilometers (x) will be paved on 10 hours:
Kilometers time (hours)
2/5 ⇔ 1 1/2
x ⇔ 10
The relationship these 3 numbers have can be described by using the <u>rule of three,</u> which is to multiply the cross quantities on the table (2/5 by 10) and then divide by the remaining amount (1 1/2):
x = ÷
x = ÷
we use
x = ÷
and we make the division:
x = ÷ =
we simplify the fraction by dividing the numerator and denominator both by 5, and we get the result:
x =
thus, in 10 hours the crew will pave 8/3 km. Which is about 2.66 km.
Answer:
<h2>
43°</h2>
Step-by-step explanation:
In a cyclic quadrilateral, the sum of two opposite angles are equal.
m<R + m<P = 180°
plugging the values:
3y + 8 + y = 180°
Combine the like terms:
4y + 8 = 180°
Subtract 8 on both sides
4y + 8 - 8 = 180 - 8
Calculate the difference
4y = 172
divide both sides of the equation by 4
4y/4 = 172/4
calculate
y = 43°
Hope this helps...
